Abstract

Dynamically displaying of a brake force is disclosed. A brake pedal force sensor can be used to generate signals indicating an amount or a level of brake force exerted on a brake pedal of a driving apparatus. Such signals can be processed to determine degrees of the brake force exerted. A set of display parameter values can be determined based on the determined degree of the brake force. The set of display parameters can include at least one value for illumination brightness, illumination area, illumination frequency, illumination color, and/or illumination style on a brake light of the driving apparatus. In certain embodiments, the display of the brake force is in a form of sliding bar and/or circular ring, and the brightness and/or the illumination area of the brake light is proportional to the determined degree of the brake force.

Dependent claims

A computer-implemented method for visually displaying brake force through a brake light installed on a driving apparatus, the method comprising:

receiving, from a pedal force sensor, an input signal reflecting a brake force applied by an operator of the driving apparatus to a brake force pedal of the driving apparatus, wherein the input signal does not indicate an absolute value of the brake force;
determining, based on the input signal, a predetermined brake force range the brake force applied by the operator belongs to, wherein the predetermined brake force range reflects a percentage value indicating a percentage relationship between the applied brake force and a maximum brake force applicable to the brake force pedal;
determining a set of one or more display parameter values based on the predetermined brake force range;
querying a status and/or a capability of the brake light;
determining whether the parameter values are implementable by the brake light based on a result of the querying;
and
in response to a determination that the parameter values are implementable by the brake light, effectuating a display of the brake light using the set of one or more display parameter and a display of the percentage value in a numeric format.
